For lightweight boxer briefs that stretch, recover and manage perspiration, there is the O Series 9" Boxer Jock from Under Armour. You will enjoy the durable comfort of a polyester-elastane blend, complemented by its four-way stretch fabrication. The stretch styling of this garment gives you a wider span of mobility in any direction. Superior moisture-wicking properties transport sweat away from skin so fabric dries much faster, keeping you dryer and fresher. Anti-odor technology also helps prevent embarrassing odors from developing over the course of the day. These unbeatable boxers are designed to be very close to the body — minus the constriction of compression — for uncompromising comfort and support.
